Which height measurement is specified for mirrors and dispensers for accessibility?

• A. 24 inches
• B. 32 inches
• C. 40 inches
• D. 48 inches

Answer: (C)

A height of forty inches is used to make mirrors and dispensers accessible to a wide range of users, including people in wheelchairs. Placing the bottom edge of a mirror at or below 40 inches ensures someone seated can see themselves without stretching or standing, and mounting dispensers so the operable part is within reach at about head-to-chest height keeps them usable without overreaching. Heights much lower (like twenty-four inches) would be awkward for most standing users and still not ideal for mirrors, while higher heights (such as forty-eight inches) would be out of reach for many seated users. Forty inches strikes a practical balance for accessibility.
